Even if you don't like Windows 8 this it's not change for the sake of change. It's change for the sake of allowing Windows to operate well on millions more devices that it doesn't currently.
I think it is quite obvious this is geared towards mobile devices. So what makes you think it will automatically scale to desktops well??? It is Microsoft we are talking about here. This is a port to desktops. Same as everyone complaining about crappy console ports to PC. Win 8s only savior is the tablet / mobile craze. That is all they care about. Hope this does not start a bad trend of going away from power users and desktops.
